TPMS Pressure Sensor Issue

[DanW]

So I had a tire pressure sensor fail on my JT. It was on the right rear at the time and was not registering pressure, triggering a ¨Service TPMS¨ message. I took it to get the tires rotated and balanced @Discount Tire. They changed it and rotated the tire/wheel to the right front. Unfortunately, it is still not registering. I took it back today and they scanned it and found it was transmitting and they went through the activation procedure again. I drove 30 minutes home on the highway and it still is not registering.

I know it is not the sensor because it has shown zip in two different locations and when it was rotated to the spare, all 4 wheel positions were registering.

So maybe there is a compatibility issue? They did say the original, which was not registering, showed a good battery. I am not sure if they checked if it was transmitting or if they could even do that.

So I´m stumped at this point. The only things I can think of are that it either the new one is defective, or maybe it is not compatible. Because the sensors pick up the other tires at all 4 positions, I think that rules out a problem on the receiver end.

So I´m wondering if I should have them replace it to see if it is a bad unit, or if I should buy a Mopar OEM sensor and have them install it.

Has anyone else had a similar issue, and if so, what was the solution?

Any suggestions will be deeply appreciated.

I see what could be a problem. There are two part numbers for the 2021 JT. One is for trucks built before 6/8/21 and another for those built 6/8/21 or after.

I think I am going to go to the dealership and get the right one and then have @Discount Tire throw it in there and see what happens.

If the sensor problem is following the location of the tire after rotate then id say safe assumption would be a sensor compatibility." They all look alike but are not the same"

Heading to the parts department this morning. I´ll post up early next week when it gets installed.

Got the new sensor. @Discount Tire getting it installed.

I should've lubed up before going to the dealership. $81.
